1 Pre-operating system management applications You can manage basic settings and features of a system without booting to the operating system by using the system firmware.
System Setup details The System Setup Main Menu screen details are explained as follows: Option Description System BIOS Enables you to configure BIOS settings. iDRAC Settings Enables you to configure the iDRAC settings. The iDRAC settings utility is an interface to set up and configure the iDRAC parameters by using UEFI (Unified Extensible Firmware Interface). You can enable or disable various iDRAC parameters by using the iDRAC settings utility.
Option Description Boot Settings Provides options to specify the Boot mode (BIOS or UEFI). Enables you to modify UEFI and BIOS boot settings. Network Settings Provides options to manage the UEFI network settings and boot protocols. Legacy network settings are managed from the Device Settings menu. Integrated Devices Provides options to manage integrated device controllers and ports, specifies related features and options.
Option Description System Management Engine Version Specifies the current version of the Management Engine firmware. System Service Tag Specifies the system Service Tag. System Manufacturer Specifies the name of the system manufacturer. System Manufacturer Contact Information Specifies the contact information of the system manufacturer. System CPLD Version Specifies the current version of the system complex programmable logic device (CPLD) firmware.
Option Description Video Memory Specifies the amount of video memory. System Memory Testing Specifies whether the system memory tests are run during system boot. Options are Enabled and Disabled. This option is set to Disabled by default. Dram Refresh Delay By enabling the CPU memory controller to delay running the REFRESH commands, you can improve the performance for some workloads. By minimizing the delay time, it is ensured that the memory controller runs the REFRESH command at regular intervals.
Processor Settings details About this task The Processor Settings screen details are explained as follows: Option Description Logical Processor Enables or disables the logical processors and displays the number of logical processors. If this option is set to Enabled, the BIOS displays all the logical processors. If this option is set to Disabled, the BIOS displays only one logical processor per core. This option is set to Enabled by default.
Option Description Configurable TDP Enables you to configure the TDP level. The available options are Nominal, Level 1, and Level 2. This option is set to Nominal by default. NOTE: This option is only available on certain stock keeping units (SKUs) of the processors. x2APIC Mode Enables or disables the x2APIC mode. This option is set to Enabled by default. Compared to the traditional xAPIC architecture, xAPIC extends processor addressability and enhances interrupt delivery performance.
SATA Settings details About this task The SATA Settings screen details are explained as follows: Option Description Embedded SATA Enables the embedded SATA option to be set to AHCI Mode, or RAID Mode. This option is set to AHCI Mode by default. Security Freeze Lock Enables you to send Security Freeze Lock command to the embedded SATA drives during POST. This option is applicable only for AHCI mode. This option is set to Enabled by default.
Boot Settings You can use the Boot Settings screen to set the boot mode to either BIOS or UEFI. It also enables you to specify the boot order. ● UEFI: The Unified Extensible Firmware Interface (UEFI) is a new interface between operating systems and platform firmware. The interface consists of data tables with platform related information, boot and runtime service calls that are available to the operating system and its loader.
Hard-disk Drive Placeholder Enables or disables the Hard-disk drive placeholder option. This option is set to Disabled by default. BIOS Boot Settings Enables or disables BIOS boot options. UEFI Boot Settings Enables or disables UEFI Boot options. NOTE: This option is enabled only if the boot mode is BIOS. The Boot options include IPv4 PXE and IPv6 PXE. This option is set to IPv4 by default. NOTE: This option is enabled only if the boot mode is UEFI.
Viewing Network Settings To view the Network Settings screen, perform the following steps: Steps 1. Power on, or restart your system. 2. Press F2 immediately after you see the following message: F2 = System Setup NOTE: If your operating system begins to load before you press F2, wait for the system to finish booting, and then restart your system and try again. 3. On the System Setup Main Menu screen, click System BIOS. 4. On the System BIOS screen, click Network Settings.
Integrated Devices You can use the Integrated Devices screen to view and configure the settings of all integrated devices including the video controller, integrated RAID controller, and the USB ports. Viewing Integrated Devices To view the Integrated Devices screen, perform the following steps: Steps 1. Power on, or restart your system. 2.
Option Description I/O Snoop HoldOff Response Selects the number of cycles PCI I/O can withhold snoop requests, from the CPU, to allow time to complete its own write to LLC. This setting can help improve performance on workloads where throughput and latency are critical. Embedded Video Controller Enables or disables the use of Embedded Video Controller as the primary display. When set to Enabled, the Embedded Video Controller is used as the primary display even if add-in graphic cards are installed.
Option Description Table 2. Slot Disablement (continued) Slot Bifurcation Option Description Slot 3 Enables or disables or only the boot driver is disabled for the PCIe slot 3. This option is set to Enabled by default. Allows Platform Default Bifurcation, Auto Discovery of Bifurcation and Manual Bifurcation Control. The default is set to Platform Default Bifurcation.
Option Description Serial Port Address Enables you to set the port address for serial device. This field sets the serial port address to either COM1 or COM2 (COM1=0x3F8, COM2=0x2F8). This option is set to Serial Device1=COM2 or Serial Device 2=COM1 by default. NOTE: You can use only Serial Device 2 for the Serial Over LAN (SOL) feature. To use console redirection by SOL, configure the same port address for console redirection and the serial device.
Option Description System Profile Sets the system profile. If you set the System Profile option to a mode other than Custom, the BIOS automatically sets the rest of the options. You can only change the rest of the options if the mode is set to Custom.This option is set to Performance Per Watt Optimized (DAPC) by default. DAPC is Dell Active Power Controller.Other options include Performance Per Watt (OS), Performance, and Workstation Performance.
System Security You can use the System Security screen to perform specific functions such as setting the system password, setup password and disabling the power button. Viewing System Security To view the System Security screen, perform the following steps: Steps 1. Power on, or restart your system. 2.
Option Description Table 4. TPM 1.2 security information (continued) Option Description all the contents of the TPM are cleared. This option is set to None by default. Table 5. TPM 2.0 security information Option Description TPM Information Changes the operational state of the TPM. This option is set to No Change by default. TPM Firmware Indicates the firmware version of the TPM. TPM Hierarcy Enable, disable, or clear the storage and endorsement hierarchies.
Option Description In-Band Manageability Interface When set to Disabled, this setting hides the Management Engine's (ME), HECI devices, and the system's IPMI devices from the operating system. This prevents the operating system from changing the ME power capping settings, and blocks access to all in-band management tools. All management should be managed through out-of-band. This option is set to Enabled by default.
3. On the System Security screen, verify that Password Status is set to Unlocked. 4. In the System Password field, type your system password, and press Enter or Tab.

System Halted! Even after you restart the system, the error message is displayed until the correct password is typed.
Option Redundant OS State Description NOTE: This option is disabled if Redundant OS Location is set to None. When set to Visible, the backup disk is visible to the boot list and OS. When set to Hidden, the backup disk is disabled and is not visible to the boot list and OS. This option is set to Visible by default. NOTE: BIOS will disable the device in hardware, so it cannot be accessed by the OS.
